WEST HOLLYWOOD, Calif.—Two U.S. Supreme Court rulings were celebrated all day at a West Hollywood gathering of gay marriage supporters.

Cheers and applause erupted Wednesday when the court struck down a law denying federal benefits to married gay couples and cleared the way for resumption of same-sex marriage in California.

The crowd grew and by evening it included hundreds of people, including many same-sex couples, dressed in red, white and blue and waving rainbow flags. One person carried a sign that said, "Today we are American."

Paul Katami, one of the plaintiffs in the case, said his court fight "was about liberty and the freedom to marry the person you love."

Equality California canvasser Brianna Eaton said it's a historic day that many people had been hoping would come.
